Undoubtedly, the acceptance of bitcoin is growing in a remarkable way, but most of the people involved in these field are people from Europe, Asia and America. For me who live in an underdeveloped country of Latin America I find it disappointing to see the little interest that people have in these technological issues, and the great ignorance that still prevails with respect to cryptocurrencies.
In addition, in these countries people have very few aspirations and do not seem interested in matters related to technology. And from what I see, in places like Africa, something similar seems to happen.
This type of educational, economic and technological limitations will only mean a delay for bitcoin to become a cryptocurrency of truly global scope and use.
I think that with the ease at which people can use bitcoin with user friendly wallets such as Electrum which still lets you control your own private keys, you really don't need that much technical expertise to use bitcoin per se anymore.
I really think that a lot of the population in these countries are not adopting bitcoin not because they don't have the means to do so, but because they are simply not aware of the fact that bitcoin exists, and there is no reason to adopt bitcoin at this stage if their country's economy is relatively stable.
It's not really a major impediment at all, but rather just a short term phenomenon of people being unaware of this technology. If the rest of the world catches on and bitcoin becomes an integral part of commercial activities on the internet, and/or their fiat currency collapses, they will have the means and need to adopt bitcoin in my opinion.
